Separate BSC Code from MSC code into separate repository
The idea is that OsmoBSC and OsmoMSC should have a separate repository (currently they are both in openbsc.git).
The question is what kind of code they still share, and how to deal with this. I guess we will only see that once we try it.
Abis/BSC related utilities like abisip-find should go with the BSC.
It's less clear what is to happen with things like the bsc_nat.
